It's a hot summer in Croatia. Vatroslav is an eternal Hungarian language student in his twenties, working as a fast food delivery driver with an employer who doesn’t pay him.

After his colleague ends up in the hospital due to Vatroslav's mistake, Vatroslav offers to take over his colleague’s job harvesting tomatoes on a small Dalmatian island, Maja Glava—formerly a stronghold of the Yugoslav army and now a site where a pro-life organization plans to open a youth camp.

On Maja Glava, Vatroslav encounters a host of colorful characters—local activists, foreign tourists, police officers, misfits, and petty layabouts—among whom stand out local dentist Irena, her stoned friend Matko, tourists Mića and Jelena from Serbia, and his hostess, Grandma Mariljka. Her late husband Vice had worked on a secret military experiment to isolate nationalist genes during the Yugoslav era, which seems linked to the increasingly frequent illnesses of the locals and the disappearances of tourists.

These and other family secrets come to light during a fishing festival when an epidemic of cannibalism erupts on the island. To save himself, Vatroslav, along with his new acquaintances, is forced to seek refuge in the JNA barracks—the same one where the evil began during the Socialist Federal Republic of Yugoslavia.
